The system does not need to be connected to the moving part of the mechanism, as movement is generated by an internal piston with bidirectional pneumatic function. Such piston, operated by a 5-way valve, moves autonomously untill it meets the obstacle, thus measuring the stopping position. Position detection is obtained by the transformation of the translation movement of the piston rod into the rotary movement of the screw, by means of screw-female screw coupling. Then the encoder turns the rotation into a sequence of electrical impulses. The piston and the encoder body need to be fi xed, i.e. must not move regardless of screw rotation. This is the reason why the cylinder has been designed with octagonal piston and properly modifi ed non-rotating piston rod.The speed of the impact against the obstacle is limited by proper calibrated reducers which are embodied in the actuator, while the translation speed can be suitably controlled by means of a standard fl ow regulator. For the indicated repeatability of reading to be guaranteed, the translation speed needs to be kept as constant as possible. Main application fi elds are: mechanisation, palletization and automation of opeating machines.
